The reason I ask is because years ago when I would restore old plastic model car kits, if the plastic windows were dull and scratched, I would steel wool them, then spray clear coat on them and they would look new and clear again. Of course heat and the elements were not a concern.

The UV protectant that I've seen used in conjunction with headlight restoration (and this is only thru recent research as I am no expert. Although I do play one on T.V.) is a very thin, clear, watery looking chemical that is misted on then wiped off. I personally wouldn't use any type of spray clear coat as I would imagine this would yellow rapidly.
I found a very good Q & A regarding the 3M kit here >
3M 02516 HeadLight Repair System
A quote from that page "In order to maintain the clarity of the lens after refinishing, Plastic Cleaner (3M 39017) and Plastic Polish (3M 39010) can be used on an as needed basis."
Hope this helps.
